[Mondrian] How to explore the dimension object used as a measure?

[Fabien Carrion]

Hi,

I would like to explore the Dimension object when it is used as a measure.

So I do this:

Schema schema = connection.getSchema();
Cube cubes[] = schema.getCubes();
for (int n = 0; n < cubes.length; n++) {
if (cubes[n].getName().equals(cubeDefaultName)) {
cube = cubes[n];
break;
}
}
Dimension dimensions[] = cube.getDimensions();
for (int n = 0; n < dimensions.length; n++) {
Hierarchy hierarchy = dimensions[n].getHierarchy();
Member member = hierarchy.getDefaultMember();
if (dimensions[n].isMeasures()) {
measuresMdx = "";
columnsMdx = " select NON EMPTY {" + member.getUniqueName() + "}
ON columns, ";
} else {
if (rowsMdx.length() > 0) {
rowsMdx.append(", ");
}
rowsMdx.append(member.getUniqueName());
}
}
StringBuffer result = new StringBuffer(measuresMdx.length() +
columnsMdx.length() + rowsMdx.length() + 50);

result.append(measuresMdx).append(columnsMdx).append("NON EMPTY
{(").append(rowsMdx).append(")} ON rows ").append("from [" +
cube.getName() + "]");


This code just display me one measure. I don't find out where are the
other measures. How can I display them?

I am using mondrian 2.3.2.8944 in a java program.

Thanks

You're only getting the first measure because you're calling

> Member member = hierarchy.getDefaultMember();

To get all members of the measures dimension you could write

> if (dimensions[n].isMeasures()) {
> Hierarchy hierarchy = dimensions[n].getHierarchy();
> SchemaReader schemaReader = schema.getSchemaReader();
> Member[] members =
schemaReader.getHierarchyRootMembers(hierarchy);

Or, just generate MDX:

> if (dimensions[n].isMeasures()) {
> columnsMdx = " select NON EMPTY {" + dimensions[n].getUniqueName()
+ ".Members}
> ON columns, ";

with the MDX : "select NON EMPTY {" + dimensions[n].getUniqueName() +
".Members} ON columns, " I get all the measures. But I don't get the
CalculatedMember. Is it the normal behaviour?

Fabien,
If you use hierarchy.getDefaultMember(), it will not solve your purpose.
I have done in following ways.
Try this.
// Measures are always returned as zeroth dimension
Dimension dimension = cube.getDimensions()[0];

mondrianSchema = connection.getSchemaReader()

// All Measure names belong to zeroth hierarchy
RolapMember[] measures = (RolapMember[])
mondrianSchema.getHierarchyRootMembers(dimension.getHierarchies()[0]);

for(int i = 0 ; i < measures.length ; i++)
{
System.out.println((measures[i].getUniqueName()));
}

Feel free to come back to me.

Thanks & Regards
Prakash

Hi,

I used both way, trying to get the measures names by
mondrianSchema.getHierarchyRootMembers(dimension.getHierarchies()[0]);
and the olap query.

I get the normal measures, which are from the fact table.
But I don't get the calculated measures.

So if my cube is:

<VirtualCube name="TrainingEmployeeCube">
<VirtualCubeDimension name="Training"/>
<VirtualCubeDimension name="Project"/>
<VirtualCubeMeasure cubeName="EmployeeCount"
name="[Measures].[Count Employee]"/>
<VirtualCubeMeasure cubeName="TrainingCount"
name="[Measures].[Count Training]"/>
<VirtualCubeMeasure cubeName="TrainingEmployee"
name="[Measures].[Count TrainingEmployee]"/>
<CalculatedMember name="Percentage of trained Employee"
dimension="Measures">
<Formula>( [Measures].[Count TrainingEmployee] ) / (
[Measures].[Count Training] * [Measures].[Count Employee] )</Formula>
<CalculatedMemberProperty name="FORMAT_STRING"
value="###.##%"/>
</CalculatedMember>
</VirtualCube>


I get [Measures].[Count Employee], [Measures].[Count Training],
[Measures].[Count TrainingEmployee]. But I don't get
[Measures].[Percentage of trained Employee]

Is there a specific way for the Calculated Members?

Thanks
